         7 . The composition of  claim 1 , wherein the composition is an emulsion having an internal fatty phase. 
     
     
         8 . The composition of  claim 1 , wherein at least one polyphenol X is present in a concentration by weight from about 1% to about 10% in the composition. 
     
     
         9 . The composition of  claim 1 , further comprising an ingredient selected from at least one rheology modifier, at least one filler, at least one additional film-forming agent, at least one humectant, and combinations thereof. 
     
     
         10 . The composition of  claim 1  wherein the emulsion has a shear modulus, G′ at 0.1% strain of at least about 150 Pa. 
     
     
         11 . The composition of  claim 1  wherein the emulsion has a yield stress of at least 7 Pa. 
     
     
         12 . The composition of  claim 1  wherein compound Y has an HLB less than six, wherein the water is present in a concentration by weight in the composition from 5% to about 70%, wherein compound X and compound Y are each independently present in a concentration by weight from about 0.5% to about 25%, and wherein the emulsion meets one or more of the following properties: has a shear modulus, G′ at 0.1% strain of at least about 150 Pa or has a yield stress of at least 7 Pa. 
     
     
         13 . The composition  claim 1 , wherein the at least one C2-C5 monoalcohol is a C2-C4 monoalcohol.
